nvcodec: Drop system installed cuda.h dependency ... and add our stub cuda header. Newly introduced stub cuda.h file is defining minimal types in order to build nvcodec plugin without system installed CUDA toolkit dependency. This will make cross-compile possible.

nvcodec: cuda.h only needs glib.h, not gst.h Just a nitpick. Also, force the compiler to use our stub header instead of searching for it in the include paths.

nvdec: Don't use default CUDA stream Async CUDA operation with default stream (NULL CUstream) is not much beneficial than blocking operation since all CUDA operations which belong to the CUDA context will be synchronized with the default stream's operation. Note that CUDA stream will share all resources of the corresponding CUDA context but which can help parallel operation similar to the relation between thread and process

This was working fine on x64 because `__stdcall` is ignored and there's no special calling convention. However, on x86, we need to use `__stdcall`.
